WordPress Migration to Multivendor Storefront

UR Requirements
Basically, we are migrating https://rosywink.com/ into another domain on same cpanel server" unitedrestaurants.com"
What "united restaurants" will do? the site has nothing to do with meals, dishes, ordering food or anything of that sort.
"United reasurants" will be a multivendor platform for restaurants to sell un-needed equipments, furniture etc..to
other fellow restaurant owners, AND for restaurant suppliers and service providers for example, restaurant equipment suppliers, linen, breads, dairy
, paper goods, accountants, violation removers, erc....

What I did for you?
I already uploaded, Wp_content folder, config file, sql
What I will do?
1- Add Dokan multivendor plugin
2- Add better messages plugin ( I do not want to use Dokan chat)
3- Clean up liberary from unused images
4- remove all products
5- remove current categories and provide new categories
6- help configuring plugins configurations and payment gateways. help only

What you will do?
- You are to edit the config file, do all url redirects and make sure new site does not refer at anytime to migrated site
- Create a page with name " Chat Room" for use with better messages
- create a field in product submit for " New, Used, NA"
- redesign current homepage sectionswise and imageswise ( to be discussed )
- I know exactly what I am doing so, please never think of outsmarting me. you know your business I know
mine, and I have been into this before you were born ( this is true, I am not young)
- Read and understand before bidding. It is a simple project despite descriptipn is so long.
Nice doing business with you.
